SIMPLE bodybuilding/weight gain guide for English-challenged person?

I have looked, and I can't find something SIMPLE for my friend Kareem. He was a waiter at my cafe in Goa. His father is a police inspector. His best opportunities for his career is to follow his father's footsteps. One problem: Kareem is scrawny. Too scrawny for academy regulations in Hyderabad. I told him I would send him a weight gain guide... I tried to tell him to lift weights and eat ice cream, etc. but it didn't really sink in.

He needs a SIMPLE guide. THAT is what I can't find. His English is not the best. His Hindi and (whatever they speak in Andre Pradech) are great, but he needs something short and to the point in English.

Anyone? I'd like to help him out. He was really nice. He just needs to gain and hold about 15 pounds to get into the academy. Not too hard, if he has the right information.
